Maybe add a couple lines (in red) near the top:

Code:
// ## configuration end
// ######################################################
// ## Do not touch code below!
   
$max_items = 10;
$item_count = 0;   
$is_item = false;
$tag = '';
$title = '';
$description = '';
$link = '';

then change function end_element like this:

Code:
function end_element($parser, $name)
{
    global $is_item, $title, $description, $link, $rss_output;
    if ($name == "ITEM")
    {
        global $item_count, $max_items;
        $item_count++;
        if ($item_count <= $max_items)
        {
            $rss_output .= "<table width='530' style='margin-left:auto; margin-right:auto; padding-bottom:10px;'>
                            <tr>
                                <td style='padding-left:15px;' align='left'><p style='font-weight:bold;'><a style='color:#FB7800;' href='" . trim($link) . "'>" . htmlspecialchars(trim($title)) . "</a></p></td>
                            </tr>
                            <tr>
                                <td><p style='color:#70CCA0'>" . htmlspecialchars(trim($description)) . "</p></td>
                            </tr>
                        </table>";
        }
        $title = "";
        $description = "";
        $link = "";
        $is_item = false;
    }
}

But this really only ignores everything after the first 10 items returned in the feed, which means that if there are more than 10 some are just going to be lost.

Thak you very much.
That worked perfect
You are mi saviour.

Popa Andrei 06-25-2012 11:57 PM
any ideea how to fecth and display in the html output the thread creation date and time?

kh99 06-26-2012 11:08 AM
You can edit the feed and put {feed:date} in the body template.

ETA: oops - I forgot we're talking about your custom reader script. Let me look at that...

OK, try this: Change function character_data() to:

Code:
function character_data($parser, $data)
{
    global $is_item, $tag, $title, $description, $link, $date;
    if ($is_item)
    {
        switch ($tag)
        {
            case "TITLE":
            $title .= $data;
            break;
            case "DESCRIPTION":
            $description .= $data;
   
            break;
            case "LINK":
            $link .= $data;
            break;
            case "PUBDATE":
            $date .= $data;
            break;
        }
    }
}

Then at the beginning of the end_element function:

Code:
function end_element($parser, $name)
{
    global $is_item, $title, $description, $link, $rss_output, $date;

then use $date in the html output. (I haven't tested this at all).

There's one more part that I missed highlighting in red - at the beginning of character_data(), you need to add $date to the global statement.

Ty its working but i think it needs a little adjustements.
Look

kh99 06-26-2012 02:01 PM
Oh, right. At the bottom of the end_element() function, where there's $title = "", $description = "", etc, add $date = "";
